An audio debounce system and method

Abstract

Embodiments of the present invention provide an audio dejittering system and method, and relate to the field of audio data processing. During the transmission of audio data, it can continuously capture the relevant parameters of the jitter time of the audio data, automatically learn different network jitter rules and environments, and select a more optimized solution for the jitter buffer according to the captured various related parameters. Adjust the size to achieve a better audio debounce effect.

Description

technical field [0001] The present invention relates to the field of audio data processing, in particular to an audio dejittering system and method. Background technique [0002] In VoIP communication, it is highly susceptible to network delay / jitter factors. Network delay will cause voice delay; in order to solve the jitter, generally increase the jitter buffer, realize the reordering of out-of-order packets, and achieve jitter smoothing. The commonly used jitter buffer technology is to set a buffer at the receiver, and when the voice packet arrives, it first enters the buffer pool for temporary storage, and then the system takes the voice packet out of the buffer pool at a stable and smooth rate, and plays it after decompression to the recipient. This buffer technology can effectively eliminate voice jitter and improve sound quality within a certain limit. The common de-jitter buffer method is to dynamically change the size of the jitter buffer. The de-jitter buffer met...

Problems solved by technology

The common de-jitter buffer method is to dynamically change the size of the jitter buffer. The de-jitter buffer method currently used is relatively simple to adjust the buffer, and the granularity of the jitter time is large, resulting in sound distortion and unsatisfactory de-jitter effect.
